Fix the following static checker warnings:
drivers/staging/imx-drm/parallel-display.c:64 imx_pd_connector_get_modes()
error: potential null dereference 'mode'. (drm_mode_create returns null)
drivers/staging/imx-drm/parallel-display.c:73 imx_pd_connector_get_modes()
error: potential null dereference 'mode'. (drm_mode_create returns null)
